Understanding Resilience
Some people look successful and resilient from the outside — they function at work, in the family, in everyday life — and only realise late how exhausted they actually are. The battery is empty, but carrying on has taken on a life of its own. Understanding resilience starts with resolving this contradiction: recognising that resilience isn’t a fixed trait you either have or don’t, but an interplay of demand, appraisal, and recovery — and that this exact interplay is something you can actually change.
Understanding Resilience Starts With a Question: What Actually Is Stress?
In everyday language, stress is almost everything: the packed calendar, the difficult conversation, standing traffic. Scientifically, though, stress isn’t a property of a situation — it’s the result of an appraisal. Psychologists Richard Lazarus and Susan Folkman coined the transactional model of stress for this: stress arises when a person judges a demand to be significant while simultaneously being unsure whether their own resources are sufficient to meet it (Lazarus & Folkman, 1984). What matters, then, isn’t the demand itself, but the relationship between it and a person’s own, subjectively judged ability to cope. Health psychologist Gert Kaluza translated this model into a simple distinction for practical use, the so-called stress triad: stressors are the external demands that can trigger strain. The stress response is what happens inside us afterwards — physically, mentally, emotionally. And personal stress amplifiers are our own attitudes and appraisals, which shape how we approach a situation and help determine how stressful we experience it to be (Kaluza, 2007). This third component is why two people can react completely differently to the same demand — a short-notice schedule change, say, or critical feedback. For everyday practice, this distinction is useful because it shows that anyone wanting to work on their stress load isn’t limited to a single lever. You can try to change the external demands, you can work on your own response, and you can examine your own appraisals. These same three angles are picked up again later, in the coaching section of this article. It’s also important to distinguish between acute and chronic stress. Acute stress is time-limited and generally unproblematic — the body activates, the demand gets handled, the system settles back down. It becomes a problem when this activation no longer subsides, because strain continues or repeats without sufficient recovery in between.How the Body Responds to Sustained Strain
In the short term, the body’s stress response is a sensible adaptive mechanism: heart rate and breathing speed up, muscles tense, the body mobilises energy. This mechanism only becomes a problem once it stays active over a longer period. Neuroscientist Bruce McEwen describes this process with the concept of allostasis: the body’s effort to establish a new equilibrium through change. When this adaptation process stays permanently active, it’s called allostatic load — the adaptation itself becomes a health burden, with demonstrable consequences for the cardiovascular system, the immune system, and the brain (McEwen, 1998). This research explains why chronic stress isn’t simply unpleasant, but can be a serious risk factor for physical health. It also explains why recovery isn’t a side issue, but the mechanism through which this load can regularly be broken down again, before it accumulates.Understanding Resilience: What It Is — and What It Isn’t
Resilience is often misunderstood as a fixed character trait: some people, the thinking goes, are simply “tougher” than others. Psychological research paints a more nuanced picture. Psychologist George Bonanno studied how differently people respond to distressing and traumatic life events, and found that a substantial share of those affected don’t go through a long period of suffering, but instead remain relatively stable or recover within a short time — without this meaning the event wasn’t distressing (Bonanno, 2004). In a later review, Bonanno and Diminich distinguish several such trajectories — from minimal impairment to delayed but ultimately successful recovery — rather than treating resilience as a single, uniform state (Bonanno & Diminich, 2013). Understanding resilience, then, starts with letting go of the idea of a fixed personality type. Resilience is therefore less a personality trait than a process with a variable course — and a process can be influenced. Psychiatrists Steven Southwick and Dennis Charney summarise several factors in their review that support this process: among them a supportive social network, the ability to appraise threatening situations as manageable, active rather than avoidant coping strategies, and a sense of meaning or purpose beyond the current strain (Southwick & Charney, 2012). None of these factors is innate or unchangeable — they can, to varying degrees, be developed.Why Recovery Matters Just as Much as the Strain Itself
Anyone who wants to understand and strengthen their resilience can’t get around recovery research. If resilience isn’t a fixed state but is decided in the interplay of strain and recovery, then recovery deserves far more attention than it usually gets in everyday life. Work psychologist Sabine Sonnentag developed the so-called stressor-detachment model for this: what matters for genuine recovery isn’t simply the time available, but psychologically switching off from work-related demands — actually letting go mentally, instead of continuing to ruminate or staying reachable during time off (Sonnentag, 2015). Someone whose mind keeps returning to an unfinished project while on holiday often barely recovers during that time, even if they’re objectively “off.” A meta-analysis of several studies by Alex Bennett and colleagues confirms this finding and sharpens it further: what matters is less the sheer duration of a recovery period than its quality — that is, whether a break is actually experienced as relaxing and detaching (Bennett et al., 2018). A short but deliberately unplugged walk without a phone can accordingly be more effective than a long evening that’s technically work-free but still shaped by exhaustion and distraction. Gert Kaluza calls this angle regenerative stress management, and groups under it everything that releases existing tension and preserves your resilience over the long term: regular relaxation, sufficient sleep, movement, maintained social contacts outside of work, and the conscious ability to enjoy small, everyday moments instead of letting them pass unnoticed (Kaluza, 2007). The point is explicitly not to avoid as many demands as possible — a life with no demands at all would hardly be desirable — but to find a balance between phases of engagement and phases of consciously stepping back from it.Exhaustion Despite Outward Success — When Performance Masks the Warning Signs
Chronic stress becomes especially treacherous where outward performance is maintained for a long time, while a deep exhaustion builds up underneath. That’s precisely what’s described by the phenomenon commonly known as burnout. The World Health Organization explicitly classifies burnout in the ICD-11 as an occupational phenomenon resulting from chronic workplace stress that has not been successfully managed — explicitly not as a stand-alone medical diagnosis or illness (WHO, 2019). This classification matters: it describes a process of exhaustion linked to chronic overload, but it doesn’t replace a proper individual assessment. Kaluza describes vividly in his book how such an exhaustion process typically develops: not suddenly, but gradually, often starting with a phase of heightened engagement. The first signs of exhaustion — worse sleep, unfamiliar fatigue, declining concentration — are frequently met with even more effort rather than a break, which intensifies the exhaustion instead of easing it. A fully developed state of exhaustion then typically shows up on several levels at once: physically, for instance as persistent fatigue and weakened resilience; emotionally, for instance as inner emptiness or irritability; mentally, for instance as declining concentration and growing cynicism; and socially, for instance as withdrawal from other people (Kaluza, 2007). For everyday life, one consequence matters above all: anyone who’s still functioning outwardly but notices early changes across several of these levels should take that seriously, rather than dismissing it as a passing rough patch. The earlier such signs are noticed and acknowledged, the sooner it’s possible to counteract them — an idea picked up again in the coaching section below.Coaching Perspective: Understanding and Strengthening Resilience
Anyone who wants to strengthen their own resilience quickly runs into a misunderstanding: the idea that there’s a single magic formula — usually some form of self-optimisation that demands even more discipline. Gert Kaluza instead proposes a model with three equally weighted angles, which he calls the three pillars of stress competence (Kaluza, 2007). The first pillar is instrumental: it addresses the external demands directly — through clear priorities, realistic time planning, delegating tasks, or deliberately setting boundaries against expectations that simply can’t be met. The second pillar is mental: it addresses your own appraisal — for instance, critically questioning inflated performance standards you hold for yourself, or viewing a demand as a challenge rather than a threat. The third pillar is regenerative, already described in the previous section: recovery, relaxation, and deliberate balance. What matters, according to Kaluza, isn’t perfecting a single pillar, but avoiding an imbalance between the three. Anyone who tries exclusively to actively control demands, without ever allowing themselves recovery, risks running themselves into the ground. Conversely, anyone who tries to compensate for strain only through relaxation, without ever addressing the actual demands or their own appraisals, tends to sidestep the real issue rather than resolve it. One helpful guide for this balance is the so-called Serenity Prayer — not surprising, given the book title “Gelassen und sicher im Stress” (“Calm and Confident Under Stress”). It goes back to theologian Reinhold Niebuhr, and Kaluza cites it as a guiding thought for a flexible approach to strain: the serenity to accept the things you cannot change, the courage to change the things you can, and the wisdom to know the difference (Serenity Prayer, Reinhold Niebuhr). Applied to the three pillars, that means: act instrumentally where you have influence, examine your own stance mentally where direct influence is lacking, and take care, regeneratively, that enough energy remains for the next demand. This same distinction — what do I actively change, versus where do I change my view of it — shows up in a similar form in other areas of personal development too. Why simply recognising a pattern often isn’t enough, on its own, to actually establish new behaviour is something we looked at more closely in I Know What I Should Do — So Why Don’t I Do It?. The same holds for stress management: insight is a necessary first step, but it takes concrete, everyday-compatible routines to turn that insight into a noticeable change.Reflection Questions for Your Own Stress Competence
- Which of my current strains could I actually change or reduce — and which do I need to learn to accept instead?
- Which of the three pillars — instrumental, mental, regenerative — do I already rely on strongly, and which do I tend to neglect?
- When did I last take a break where I genuinely switched off mentally, instead of just being formally “off”?
- Which of the typical exhaustion signals — physical, emotional, mental, social — have I noticed more strongly in myself lately?
Frequently Asked Questions
Is resilience an innate trait?
Understanding resilience here mostly means separating disposition from process. No — not exclusively, at least. Research describes resilience more as a process with varying trajectories than as a fixed character trait. Individual differences do play a role, but key influencing factors like social support, appraisal patterns, and coping strategies can be developed.Does good stress management mean having as few demands as possible?
No. A life with no demands at all isn’t considered desirable in stress research — demands are also opportunities for development. What matters is the balance between phases of effort and phases of genuine recovery, not avoiding strain altogether.How can I tell the difference between normal exhaustion and the early stages of burnout?
There’s no single, universally valid criterion, and a remote diagnosis is never credible anyway. One useful signal, though, is when signs of exhaustion appear across several levels at once — physical, emotional, mental, and in withdrawal from other people — and persist over time despite attempts to recover. In that case, professional support makes sense.Does more exercise or relaxation alone help against chronic stress?
Regenerative strategies like movement and relaxation matter, but according to Kaluza’s three-pillar model they’re often not enough on their own if the triggering demands or your own appraisals stay unchanged. Sustainable stress management usually combines all three angles.Conclusion
Understanding resilience means letting go of the idea that resilience is a fixed, innate trait. Instead, research shows: stress arises in the relationship between a demand and perceived ability to cope, chronic strain without sufficient recovery has demonstrable health consequences, and exhaustion can hide behind outward functioning for a long time. Anyone who wants to work on this has, in the three pillars of stress competence — instrumental, mental, regenerative — a model at hand that doesn’t rely on a single solution, but on a deliberate balance between active action, changed appraisal, and genuine recovery.Selected Scientific Sources
